Week 7 and 8
Nice work on keeping your data updated. Try to include DNA sizes in your caption and also where exactly are you with virtual work? Thank you. -Max 10/21/13

A master plate was made from nine of these colonies that grew and 5ml cultures were grown up the night before and midiprepped. All nine samples were nanodropped then sent to DNA sequencing to check which were positive clones.

Figs 1, 2: Nanodrop measurements of the second and third colonies from master plate after midiprep. Measurements from all nine samples were taken, and concentrations ranged from 50 ng/ul to 110.5 ng/ul

DNA sequencing order number: 96613


10/14/13
The two plates with pNIC-Bsa4 with STPP2b in DH5-alpha had a total of eleven colonies successfully grow.

DSC_0034.jpg

Fig. DH5-alpha with pNIC-Bsa4 + STPP2b on LB agar+kanamycin+sucrose plates

These eleven colonies should have the recombinant plasmid successfully transformed into them. A master plate was made from nine of these colonies and 5ml cultures were grown up overnight and midiprepped.

10/11/13
pNIC-Bsa4 was cut with restriction enzyme BsaI. The results were PCR cleaned up then run on a gel.

Lane 1: Empty
Lane 2: 1kb ladder
Lane 3: empty
Lane 4: pNIC-Bsa4 cut with RE BsaI

The lane with the cut plasmid has two clear bands, showing that the plasmid did cut properly at the sites it was supposed to cut at, and the SacB gene has been cut out of the plasmid, leaving the backbone and ends where our target gene STPP2b can be ligated into.

The rest of the cloning procedure was carried out, and the recombinant plasmid transformed into DH5-alpha competent cells and plated onto LB+kanamycin+sucrose plates and placed in the 37 degree incubator.

10/10/13
After pNIC-Bsa4 in DH5-alpha was grown upn LB media overnight, cells were spun down and midiprepped.

A good concentration of the pNIC vector is evident from the Nanodrop.

Gel of PCR squared reaction

Lane2: 1kb ladder
Lane3: secondary PCR
Lane 4-7: PCR squared reaction (annealing temp. 59 degrees)

Clear bands were seen in the PCR squared reaction, and PCR cleanup was performed on the results. Moving forward to cloning.

Week 5 and 6
        • Good data but try to add more detail into your caption and analysis. Thank you. -Max 10/07/2013
10/03/13
Gel of PCR squared reaction, changed annealing temperature to 59 degrees

Bands are still too faint. Will compare conditions with group member and troubleshoot.

Lane 2-5: PCR squared product

Very faint bands visible at proper gene length, particularly in lane 3. Redo PCR squared with annealing temperature of 59 degrees celsius that Anita used which worked.


Week 3 and 4
Ariel - ok keep moving forward with your cloning work. We want to get a clone soon. Dr. B 100113

Fall '13 start

Ariel - good job. - Dr. B 071713


Things To Do:
Submit to DNA Sequencing
Analyze DNA Sequence Exercise
PCR of pGBR22
Red OR Green PCR
PCR of pNIC-Bsa4 with pLIC-for and pLIC-rev primers

7/17/13
pNIC PCR gel
ac47386pNicPCR.JPG
Fig. 5: PCR gel for pNIC plasmid with pLIC for/rev primers

Lane 1: 100bp ladder
Lane 2: Sample 1 (Lowest concentration template)
Lane 3: Sample 3 (Highest concentration template)*
Lane 4: Sample 2 (Next highest concentration template)*
Lane 5: Sample 4 (0 ng concentration template)
Lane 6: SKIP
*mistakenly loaded in non-sequential order


7/16/13
mCherry PCR gel
ac47386mcherry2pcr.JPG
Fig. 4: PCR gel for pmCherry plasmid

Lane 1: SKIP
Lane 2: 100bp ladder
Lane 3: Sample 1 (0.0112 ng template with for primer VDSR1/rev primer VDSR2)
Lane 4: Sample 2 (0.112 ng template with for primer VDSR1/rev primer VDSR2)
Lane 5: Sample 3 (1.12 ng template with for primer VDSR1/rev primer VDSR2)
Lane 6: Sample 4 (0 ng template with for primer VDSR1/rev primer VDSR2)
Lane 7: Sample 5 (0.0112 ng template with M13 for/rev primer)
Lane 8: Sample 6 (0.112 ng template with M13 for/rev primer)
Lane 9: Sample 7 (1.12 ng template with M13 for/rev primer)
Lane 10: Sample 8 (0 ng template with M13 for/rev primer)

Lane 6 (Sample 4) should not have a visible band present in it, and this may be evidence of contamination or some of the sample from Lane 5 moving into Lane 6

Lane 4: Sample B (3 ng of template)
Lane 5: Sample C (30 ng of template)
Lane 6: Sample D (0 ng of template)
